- openapi.yml: declare default: false on ServiceTargetOptions.direct_upstream
so generated clients/validators reflect the documented default.
- proto/proxy_service.proto: ValidateTunnelPeer doc + denied_reason list
said "distribution_groups" (bearer-auth field) but the actual gate is
service.access_groups. Replaced both occurrences to match the code path
in checkPeerGroupAccess.
- peers/manager.go (GetPeerWithGroups) + users/manager.go (GetUserWithGroups):
on store error after a successful first lookup, both now return
(nil, nil, err) so callers can't get a valid entity alongside a non-nil
error.
Findings skipped with reasons:
- embedded.go merged CLI/Dashboard redirect URIs: pre-existing on
origin/main, not introduced by this PR.
- account_mock.go MarkPeerDisconnected zero-time UnixNano: same — pre-existing.
- openapi Service schema if/then conditionals: Go-side Validate() already
enforces these invariants (Private + non-empty AccessGroups, mode=http,
mutually-exclusive with bearer), and oapi-codegen on OpenAPI 3.1.x
doesn't honour allOf/if/then anyway.
- *.patch / *.diff / b-n-p.sh: untracked personal artifacts, not part of
any commit.
Reinstates the SyncMappings RPC that landed on origin/main and the
client-side fallback to GetMappingUpdate.
- proto: SyncMappings RPC + SyncMappingsRequest{Init|Ack} +
SyncMappingsResponse messages.
- management proxy.go: SyncMappings server handler, recvSyncInit,
sendSnapshotSync (per-batch send-then-wait-for-ack), drainRecv,
waitForAck; proxyConnection.syncStream + sendResponse routes the
same sendChan onto the bidi stream when set.
- proxy/server.go: trySyncMappings + handleSyncMappingsStream that
acks after each batch is processed; outer loop tries SyncMappings
first and falls back to GetMappingUpdate on Unimplemented.
Capabilities lifted into proxyCapabilities() so both code paths
use the same flags.
Adds a new "private" service mode for the reverse proxy: services
reachable exclusively over the embedded WireGuard tunnel, gated by
per-peer group membership instead of operator auth schemes.
Wire contract
- ProxyMapping.private (field 13): the proxy MUST call
ValidateTunnelPeer and fail closed; operator schemes are bypassed.
- ProxyCapabilities.private (4) + supports_private_service (5):
capability gate. Management never streams private mappings to
proxies that don't claim the capability; the broadcast path applies
the same filter via filterMappingsForProxy.
- ValidateTunnelPeer RPC: resolves an inbound tunnel IP to a peer,
checks the peer's groups against service.AccessGroups, and mints
a session JWT on success. checkPeerGroupAccess fails closed when
a private service has empty AccessGroups.
- ValidateSession/ValidateTunnelPeer responses now carry
peer_group_ids + peer_group_names so the proxy can authorise
policy-aware middlewares without an extra management round-trip.
- ProxyInboundListener + SendStatusUpdate.inbound_listener: per-account
inbound listener state surfaced to dashboards.
- PathTargetOptions.direct_upstream (11): bypass the embedded NetBird
client and dial the target via the proxy host's network stack for
upstreams reachable without WireGuard.
Data model
- Service.Private (bool) + Service.AccessGroups ([]string, JSON-
serialised). Validate() rejects bearer auth on private services.
Copy() deep-copies AccessGroups. pgx getServices loads the columns.
- DomainConfig.Private threaded into the proxy auth middleware.
Request handler routes private services through forwardWithTunnelPeer
and returns 403 on validation failure.
- Account-level SynthesizePrivateServiceZones (synthetic DNS) and
injectPrivateServicePolicies (synthetic ACL) gate on
len(svc.AccessGroups) > 0.
Proxy
- /netbird proxy --private (embedded mode) flag; Config.Private in
proxy/lifecycle.go.
- Per-account inbound listener (proxy/inbound.go) binding HTTP/HTTPS
on the embedded NetBird client's WireGuard tunnel netstack.
- proxy/internal/auth/tunnel_cache: ValidateTunnelPeer response cache
with single-flight de-duplication and per-account eviction.
- Local peerstore short-circuit: when the inbound IP isn't in the
account roster, deny fast without an RPC.
- proxy/server.go reports SupportsPrivateService=true and redacts the
full ProxyMapping JSON from info logs (auth_token + header-auth
hashed values now only at debug level).
Identity forwarding
- ValidateSessionJWT returns user_id, email, method, groups,
group_names. sessionkey.Claims carries Email + Groups + GroupNames
so the proxy can stamp identity onto upstream requests without an
extra management round-trip on every cookie-bearing request.
- CapturedData carries userEmail / userGroups / userGroupNames; the
proxy stamps X-NetBird-User and X-NetBird-Groups on r.Out from the
authenticated identity (strips client-supplied values first to
prevent spoofing).
- AccessLog.UserGroups: access-log enrichment captures the user's
group memberships at write time so the dashboard can render group
context without reverse-resolving stale memberships.
OpenAPI/dashboard surface
- ReverseProxyService gains private + access_groups; ReverseProxyCluster
gains private + supports_private. ReverseProxyTarget target_type
enum gains "cluster". ServiceTargetOptions gains direct_upstream.
ProxyAccessLog gains user_groups.
Remove client secret from gRPC auth flow. The secret was originally included to support providers like Google Workspace that don't offer a proper PKCE flow, but this is no longer necessary with the embedded IdP. Deployments using such providers should migrate to the embedded IdP instead.
* **New Features**
* Access logs now include bytes_upload and bytes_download (API and schemas updated, fields required).
* Certificate issuance duration is now recorded as a metric.
* **Refactor**
* Metrics switched from Prometheus client to OpenTelemetry-backed meters; health endpoint now exposes OpenMetrics via OTLP exporter.
* **Tests**
* Metric tests updated to use OpenTelemetry Prometheus exporter and MeterProvider.
CLI: new expose command to publish a local port with flags for PIN, password, user groups, custom domain, name prefix and protocol (HTTP default).
Management/API: create/renew/stop expose sessions (streamed status), automatic naming/domain, TTL renewals, background expiration, new management RPCs and client methods.
UI/API: account settings now include peer_expose_enabled and peer_expose_groups; new activity codes for peer expose events.
